WINDOW-SASH HOLDER.

SPECIFICATION forming part of Letters Patent No. 584,310, dated June 8,1897.

Application filed August 17, 1896. Serial No. 602,955. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM II. KOONS, a citizen of the United States,residing at Bath,

in the county of Northampton and State of My invention relates tocertain new and useful improvements in sash-holders, the object of thesame being to provide a simple and I cheaply-constructed device of thischaracter whereby window-sashes may be readily raised or lowered andlocked at any point Within their range of movement.

The invention consists of a window-sash having a recess or socket in itsouter edge, a dog having a cam-face pivoted in said socket andprojecting outwardly from the edge of said sash, a pin pivoted to theend of said dog and projecting through aslot in the inner edge of saidwindow-sash, and a spring surrounding said pin for normally urging saiddog to its outer position.

The invention is clearly illustrated in the accompanying drawings, inwhich-- Figure 1 representsafront elevation, partly in section, of awindow frame and sash with my improved fastening device secured in thelatter. Fig. 2 is a view of the outer edge of the sash.

3 5 Like reference-numerals indicate like parts in both views.

The window-frame 1 has the sash 2 slidingly mounted therein, both beingof the usual form of construction except as hereinafter set forth. Thesash 2 has formed in its outer edge a recess or socket 3, in which ispivotally mounted a dog 4, having a cam-face which projects slightlybeyond the outer edge of said sash. Pivoted to the free end of said dogis a rod or bar 5, which extends inwardly through a slot or opening Ginsaid sash and has formed upon its inner end a knob or handle 7.Surrounding the rod or pin 5 and engaging the shoulder on the inside ofthe socket 3 is a coilspring 8, which tends to normally urge the dog 4outwardly.

My'improved sash-holder has been shown in the drawings in connectionwith the lower sash of a window. It will thus be seen that the sash 2 isfree to be moved upwardly, but 5 that its downward movement is preventedby reason of the engagement of the dog 4, projecting outwardly from theedge of said sash, with the inner surface of the window-frame 1. Thegreater the pressure that is applied to force the sash 2 downwardly thestronger the same will be resisted by the dog at by reason of thecam-shaped face thereon. If it be desired to lower said sash, it may bereadily done by drawing inwardly the rod or bar 5, which will releasethe dog 4 from engagement with the inner surface of the window-frame 1.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination with a window-frame having smooth inner edges, of a sashslidingly mounted therein having a recess or socket in its outer edge, acam-faced dog pivoted in said socket, a rod or pin pivoted to the end ofsaid 7 5 dog and projecting inwardly through a slot or opening in saidsash, and a coil-spring surrounding said rod, whereby said dog isnormally urge-d outwardly into engagement with the inner surface of saidwindow-frame, and whereby the same may be released therefrom,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

WILLIAM H. Koons.
